چکیده

رویکردی نوین برای بررسی تغییرات در فرآیند شبیه‌سازی ساختاری یک پایدارکننده ژیروسکوپی سه‌محوره حامل دوربین، ارائه شده است. روند ارائه شده، شامل تصمیم‌گیری مدیریتی و نحوة شناسایی بهترین مسیر فرآیند بررسی تغییرات می‌باشد. ربات نمونه فانتوم با 32 مؤلفه که نیمی از آنها مربوط به هندسه ساختار پرنده و نیم دیگر مربوط به لَق‌لَقه (گیمبال) سه‌محوره هستند انتخاب شده است. پیوندهای ساختاری بین عناصر با فرض تقارن در یک ماتریس‌ ساختار طراحی قرار می‌گیرند. یک مقدار تأثیر تغییر ثابت برای همه پیوندها و یکی از سه مقدار، 3/0، 5/0 و 8/0 بترتیب برای احتمال تغییر پایین، متوسط و بالا اندازه‌گیری و در ماتریس‌ها لحاظ شده است. به علاوه، مجموعه‌ای از شاخص‌ها برای کمک به طبقه‌بندی مولفه‌های گوناگون سیستم به عنوان پذیرنده یا بازتابنده تغییر، ایجاد و یک شاخص انتشار تغییر نرمال، قدرت نسبی هر مولفه را در طیف جذب کننده تا افزاینده با ضریب بین 1- تا 1+ معرفی شده است. این روش بر روی ربات نمونه پیاده‌سازی شده است
